Cavaliers coach David Blatt’s basketball bloodlines were on display last Friday in France, and they’re looking pretty doggone good.

After all, Tamir Blatt scored six points and passed for six assists in the FIBA European U18 All-Star Game, played at Pierre Mauroy Stadium in Lille, just a few hours before the EuroBasket 2015 semifinal between Serbia and Lithuania.

Tamir, 18, is a 5-foot-11 point guard who was selected to the All-Star fesitivites after helping guide Israel to the silver medal at the U18 European Division Championship in Division B.

He has actually been playing with 18-year-olds since the age of 15, so his recent success isn’t exactly a surprise.

Nor is it a shocker when you consider his father is one of the most successful coaches in international basketball history and led the Cavs to the Finals in his first NBA season.

Before that, David Blatt spent nine years as a point guard in the Israeli pro leagues.

“It’s amazing … he gives me all these tips, how to work hard and never give up. I’m blessed to have him as my father,” Tamir told the official EuroBasket 2015 website. “I take from him that he works really, really hard — he’s in the gym for hours, trying new things, and that’s what I try to copy.”

The younger Blatt also relayed that he was “proud of” his dad for directing the Cavs to their first Finals appearance since 2007.

As for his own career, Tamir returns to Israel this season, where he will play for Hapoel Tel Aviv in Division A.

“I hope I get some opportunities to get some minutes,” he told EuroBasket 2015. “I will do my best. I believe I can play at this level.”

And just in case you’re wondering, Tamir becomes NBA Draft eligible in 2019.
